16 Claims.

Our invention relates to an improvement in oil burners and has for one purpose the provision of an oil burner which may be secured to the outside of a stove, furnace, or range.

Another purpose is the provision of a pot type burner in which the axis of the pot is horizontal or at least substantially deflected from the vertical.

Another purpose is the provision of an ifhproved pot type burner in which the pot is eniployed to control the inflow of air and separate means are employed for receiving the fuel to be vaporized by the heat of combustion in the pot.

Another purpose is the provision of a burner which may be readily applied to and'removed from heaters, stoves, or the like.

Another purpose is the provision ofa burner in which a liquid fuel is delivered to a vaporizing element which is preferably open or partially open, and which is substantially surrounded by and preferably spaced from a vaporizing housing or shell.

Other purposes will appear from time to time in the course of the specification.

We illustrate our invention more or less diagrammatically in the accompanying drawingswherein:

Fig. 1 is a plan view of our burner as applied to a cook stove;

Fig. 2 is a vertical section on a larger scale, taken along the line 2--2 of Figure 1;

Fig. 3 is a top plan view of the structure shown in Fig. 2;

Fig. 4 is an end elevation with parts in vertical section;

Fig. 5 is a plan view on a smaller scale, with parts in horizontal section, of a modified form of the device;

Fig. 6 is a section on an enlarged scale along the line 6-45 of Fig. 5; and

Fig. 7 is a section along the line 1-4 of Fig. 6.

Like parts are indicated by like symbols throughout the specification and drawings.

It will be understood that, whereas the invention is shown as applied to a cook stove, it may be applied to any other suitable heating unit, such as a furnace or a space heater.

Referring to the drawings, I generally indicates a heater to which the burner is applied. 2 is any suitable front member of such a heater, with an inlet aperture 3. 4 indicates grate bars of a conventional cook stove to which the burner is applied, but the bars have no function when our heater is used, and may be removed. 5 is stove. The plate 5 is provided with any suitable spacing means, for example lugs 8. Against these is drawn a burner proper which includes the abutting flame ring 9, herein shown as having a central flame aperture ll! of substantially smaller diameter than the aperture 1 of the plate 5.

II is an inwardly extending annular flange spaced inwardly somewhat within the aperture 1 to provide an air inlet ring or clearance I 2. Associated with the flame ring 9 is an outer cylinder l3, with its end I4 and air inlet aperture l5. I6 is a burner pot with an end I! and a generally cylindrical side wall formed with a plurality of primary air'inlet apertures I8 located at various distances from the end I1. If-

desired, the end H may also have air inlet apertures. Any suitable means for admitting secondary air may be employed, but we illustrate a single row of secondary air inlets l9 which are inwardly tilted toward the open end of the pot. Also, the clearance or gap l2 may be used to admit secondary air.

20 is a vaporizing pa herein shown as open topped. 2! is a fuel pipe extending thereto and also adapted to serve as a support therefor, although the pan may be additionally supported or centered by a connection with the side or bottom of the pot. We illustrate for example in Fig. 2 a clip 22, which may be welded or otherwise secured to the pan 20 and may be welded or bolted, as at 23, to the pot bottom 11. The fuel pipe 2! is shown as extending to a T-connection 25, by which it is connected to any suitable float chamber or other fuel control device, indicated at 26.

The rate of flow may be controlled for example by the exterior manual element 21, although it will be understood that the control may be automatically maintained as desired.

Any suitable means not herein shown in detail may be employed for delivering fuel from a suitable source to the chamber 26, and a float valve or other suitable means may be employed for maintaining a predetermined oil levl within the chamber 26. The chamber 26 and its associated parts may be mounted upon the outer member I 3, for example by brackets 28. It will be understood, of course, that the control chamber 2 6'. may be otherwise supported, but it is advanftageous that the entireunit be mounted on or supported, directly or indirectly, upon the heater unit or upons'the late- 5,.js'o that the entirestruca I ture mjay be unitarily withdrawn from the stove. Any convenient means for securing the structure to' the stove may be employed, but we illustrate .for example tie rods 30, screw threaded to the 'pljate5 and providedwi'thupturned locking ends "3|, abutting against the bottom it of the outer cylinder. Aligning or centering studs 32, in ad- -dition to the tie rods, may be provided.

It will be understood that any suitable means for supplying air under pressure may be employed. As shown in Fig. 5 and following, we illustrate a preferably removable booster motor and fan unit, and it will be understood that such a unit may be inserted through or positioned in the aperture l5, as in the form of Fig. 2. Longitudinal vanes 33 are provided in the space between the cylinder I3 and the pot It to assist in directing air longitudinally through said space and for preventing eddy currents. In the form of Fig. 5 and following, the vaporvizing pan 40 is mounted on a generally vertical pan may be varied. As will be clear from Fig; 5,.

it may be located adjacent the bottom I] of the pot, or may be positioned substantially nea'rer the flame aperture Hi. It will be observed also that in the pot as shown in Fig. 7 the secondary air inlet apertures H! are omitted, and thegap from the pot-p In the form of Fig.6,- a shield-fillsinterposed between the control-,or fl'o'at chamber Iii-land the beaten; and it will'be understood thatasimilar shield may,.if desired, be employed in-;con-' nection with the form of Fig. 2 and following.

The motor fan unit, including the motor housing 50, a fan 5i, and a securing clip 52, is 'illus trated in Figs. 5 and 7. Any suitable conductive connection may be provided, and'it will be understood that when the fan 5| is in motion, air

under pressure is drawn through the aperture l5 into the space between the pot and the outer, cylinder l3, and the air pressure is thereby increased.

, the motor and fan unit is removed or left 1 switched offJfOnc'e .combustionls initiated, the primary'a'ir-admitted through the apertures IB ;mixes with the hydrocarbon vaporized by the flame aperture Hi. If the fuel supply is kept to a minimum, the apertures l8 will admit also sufflcient air for the secondary air supply, and the completed mixture will burn within the pot not far from the top of the pan 40. When the fuel supply is increased, the apertures it provide primary air for the mixture, and the secondary air to complete the mixture'is'idelivered either through the apertures." 19 of the-form of Fig. 2, or through the gap I2 between the members 5 and II. The amount of fuel which can be vaporized and burned can be increased by the employment of means for increasing the air pressure or air passage through the device, and the practical means for that purpose is the motor and fan unit shown in Figs. 5 and 7. When full air pressureis used in conection with maximum fuel oil delivery, a blast of flame extends generally horizontally into the stove, and in prac: tice is of suflicient length fully to heat the stove cmnpartment illustrated .at"X-;i-nFig. 1.

It will I be "observed that; a the primary air -is admitted all the way around'the vaporizing pan; or vessel IU bOlI-h above-and below it; the forms of thedevice herein shown; thebottor'n jfl is left unbroken, but it will befundejrstood that air may, ifdesired;-be-jadmittedthroug bottom...
